A21-6GN3501080BA T15-6GN3501080 EV NAO Ceramic Brake Pads for Chery Omoda 5

A21-6GN3501080BA T15-6GN3501080 Front Brake Pads for Chery Omoda 5 EV NAO Ceramic Composite

Product Introduction

Calibrated to interface with the single-motor, front-wheel-drive dynamics of the Chery Omoda 5 EV chassis, these steering-axis braking components serve as a standardized mechanical replacement for global automotive distribution channels. The friction formulation is chemically adapted to sustain steady frictional coupling during the frequent transitions between electronic motor deceleration and mechanical pad engagement. Designed to fit the exact geometric parameters of the original factory caliper hardware, the modules operate within the designated noise-suppression limits required to prevent high-frequency squeal from entering the non-combustion passenger cabin. This material matrix provides international procurement logistics networks, bulk parts importers, and professional workshop technicians with a verified, field-ready replacement component optimized for standard fleet maintenance lifecycles under regular urban commuting conditions.

Specification

Front-Axis Braking Matrix: Chery Omoda 5 EV Technical Attributes
1. Front Knuckle Mechanical Alignment
This steering-axis braking component is dimensioned specifically for the front caliper infrastructure of the Chery Omoda 5 EV chassis. The steel backing plates are stamped to interface directly with the factory carrier slides according to original equipment reference indicators A21-6GN3501080BA and T15-6GN3501080. By restricting physical clearance to standard production tolerances, the assembly prevents vertical rattle and localized binding within the carrier housing, supporting normal pad displacement parameters without requiring workshop layout modifications.

2. Friction Cohesion Under Intermittent Thermal Loads
The specialized NAO ceramic composite formulation is synthesized to address the operational profiles unique to single-motor electric platforms. Because the Orowa/Omoda 5 EV platform relies on regenerative deceleration for routine speed reduction, the mechanical friction lining is subject to prolonged low-temperature exposure punctuated by abrupt mechanical braking requests. This material matrix maintains a stable friction boundary layer, preventing the low-velocity surface glazing that typically induces high-frequency acoustic feedback during urban start-stop transit.

3. Thermal Displacement & Dissipation Limits
Engineered to withstand the kinetic energy dissipation requirements of an elevated front-axle load, the pad architecture utilizes a standardized structural layout. The compound minimizes thermal torque fading under sequential non-competitive decelerations, sustaining consistent hydraulic feedback during extended downhill gradients or highway speed transitions. The backing assembly features a high-density insulating barrier layer that restricts localized thermal energy transfer from the friction block to the caliper piston seals, mitigating the risk of fluid vulcanization under daily operational constraints.

4. Controlled Interfacial Erosion Rates 
Developed to assist international trade distributors and bulk procurement buyers with predictable maintenance asset lifecycles, the compound exhibits a regulated, low-dust wear curve. The formulation incorporates a low-copper material configuration aligned with international environmental restrictions. By maintaining a uniform, non-abrasive contact path against the brake rotor, the formulation reduces un-loaded rotor face erosion, sustaining standard fleet service intervals while minimizing particulate accumulation on adjacent steering components.

5. Mechanical Acoustic Warning Intimation
The front friction modules are equipped with a native mechanical wear alert shim (acoustic squealer) integrated directly onto the steel backing core. When friction material wear reaches the predetermined replacement threshold, the mechanical indicator contacts the rotor edge to generate a specific, localized acoustic signal during rotation. This non-electrical warning configuration provides reliable, battery-independent mechanical tracking for workshop technicians during routine vehicle inspections.

Installation & Technical Deployment Guide
For DIY Buyers (Quick Overview):
Secure the vehicle on proper jack stands, ensuring space away from the battery pack.
Turn off the EV fully and keep the smart key at least 5 meters away to avoid automatic brake caliper activation.
Open the brake fluid reservoir cap under the front hood to check levels before pushing the caliper pistons back.
Clean all slider tracks with a wire brush, install the new pads, and torque to specification.
Crucial EV Tip: After installing, switch your Omoda 5 EV’s driving mode to "Regen Off/Low" for the first 30 km to let the pads brake in naturally using mechanical friction.

Steering-Axis Mechanical Insertion & Fluid Stabilization Procedures: Chery Omoda 5 EV
1. Powertrain Inactivation & Structural Elevation

Electrical Neutralization: Prior to hardware isolation, position the vehicle on an entry-rated chassis lift. Ensure the primary high-voltage ignition system is completely deactivated and keys are isolated from the proximity detection radius to prevent unexpected automated caliper piston initialization cycles or parking brake actuator tracking during disassembly.

Chassis Point Verification: Secure the hoist pads precisely at the factory-designated front structural lift markers, verifying absolute physical clearance from the under-floor traction battery enclosure sides to prevent cosmetic or structural distortion to the energy cell matrix.

2. Fluid Containment Monitoring & Caliper Uncoupling

Reservoir Volume Check: Remove the master cylinder fluid reservoir cap located in the front non-combustion bay. Monitor the fluid level continuously before and during piston compression to prevent overflow contamination onto surrounding electronic wire harnesses.

Linkage Isolation: Extract the steering-axis wheel assemblies. Unbolt the floating guide slide bolts from the front hub knuckle. Suspend the heavy iron caliper housing using an engineering tension-free carrier hook attached to the upper chassis framework, ensuring no strain or twisting forces impact the flexible high-pressure fluid delivery lines.

3. Controlled Slide Desaturation & Geometric Insertion

Friction Bed Purging: Slide the degraded friction elements out of the carrier slots. Apply a highly volatile, residue-free chemical brake cleaner to dissolve cumulative metallic wear dust, atmospheric road salts, and localized oxidation. Use a wire brush to restore the stainless-steel slide channels to a smooth, flat metal profile.

Parallel Piston Compression: Deploy a calibrated flat-face compression tool to press the caliper piston back into its housing under a slow, progressive force, preventing back-pressure spikes within the electronic hydraulic brake booster components. Fit the new front-axis friction modules natively into the clean channels, ensuring the pre-fixed multi-layer acoustic dampening shims sit perfectly flat against the rotor face. Torque all hardware strictly to factory technical specs.

4. Hydraulic Stabilization & Decouer Burnishing

Hydraulic Linear Reset: With the vehicle stationary, perform a sequence of controlled, deliberate, full-stroke depressions of the brake pedal to advance the caliper pistons progressively until the friction lining makes unified contact with the rotor surface.

Friction Bedding Separation Strategy: To achieve a valid friction transfer layer given the Omoda 5 EV’s heavy reliance on motor deceleration, configure the driving matrix through the cockpit interface to its lowest possible energy recovery setting (Regen Off/Low) for the initial testing phase. Conduct a progressive series of moderate, non-emergency speed-reduction stops on a low-traffic route to burnish the composite ceramic formula smoothly, preventing localized thermal glazing.

Operational Warranty & Commercial Return Guidelines
1. Standard Material Quality Warranty (12 Months / 30,000 km)
We provide a limited manufacturing warranty covering our front brake pads for 12 months or 30,000 kilometers (whichever milestone occurs first from the logged date of replacement).

What is Covered: This guarantee covers confirmed factory-level structural defects only. This includes direct hardware exchange if you experience friction material separation (delamination) from the steel backing plate, abnormal cracking within the ceramic mixture under regular commuting, or stamping size errors that physically prevent the pads from sliding smoothly inside your original car calipers.

What is Not Covered (Warranty Voids): To keep this warranty valid, your vehicle’s braking system must be properly maintained. This coverage does not apply to: uneven wear caused by seized or un-serviced caliper guide pins; surface glazing (hardening) due to skipping the recommended low-regen break-in process; pads installed on heavily warped or grooved brake rotors; or premature damage to the mechanical wear warning clip caused by road debris or stone entrapment.

2. Ordering, Shipping & Batch Verification Rules
168-Hour Return & Inspection Window: Whether you are buying a single set for your personal EV or stocking up a regional workshop inventory, all shipments must be inspected within 168 hours (7 days) after delivery. If you receive an incorrect part number or notice any shipping damage, contact our trade support team within this period. To qualify for a stock adjustment or credit exchange, the items must remain unmounted, unsoiled by mechanical grease or anti-squeal compounds, and preserved in their original localized packaging boxes.

Digital Catalog & Parts Matching Support: For workshop managers, online store operators, and small fleet buyers, we eliminate parts-matching guesswork. We provide detailed 2D dimension blueprints and digital compatibility matrices (CSV/Excel format). This allows your inventory system or local mechanic to quickly verify fitment against various regional car trim variants without needing to unpack the physical boxes.

Direct Workshop Technical Liaison: If your local mechanic or your own repair team has questions about mechanical wear clip placement, caliper piston compression limits, or pad seating techniques, our technical support line is open to assist professional installers in securing proper component alignment.
